MUMBAI, India, Oct. 5 -- Intellectual Property India has published a patent application (202611101908 A) filed by Rishabh Singh Malik on August 24, 2026, for Continuous Thermochemical Reduction System And Method For Upgrading Iron Ore And Tailings.
Inventors include Rishabh Singh Malik; and Sanjeev Kumar Malik.
The application for the patent was published on October 02, 2026, under issue no. 40/2026.
Abstract: A continuous thermochemical reduction system (100) and method (300) upgrade low-grade paramagnetic iron ore or tailings into high-grade iron concentrate with zero carbon footprint. A rotary kiln (110) pre-heats an ultrafine feed, which passes through a hermetically sealed first integration unit (120) into a hydrogen reduction zone (130) operating at 450°C to 650°C. A bottom sparger header (132) delivers green hydrogen directly to the feed, while mechanical mesh lifters (134) fluidize particles to prevent sticking. The reduced ferromagnetic magnetite passes through a hermetically sealed second integration unit (140) into a cooling zone (150), where it is indirectly cooled below 100°C under an inert atmosphere using a thermic fluid. The cooled magnetite is milled to liberation size below 50 microns in a wet ball mill (160) with a classifier (162), washed in a primary thickener (170), and separated by low intensity magnetic separators (180) to isolate concentrate exceeding 63% Fe(T).
